A of the form of politics is the discipline, discipline, honesty a

11、nd discipline, discipline of the masses, work discipline and discipline of life. It can be said is to cover the party activities. Second is the discipline method separately, Ji, concentrated on the discipline. The revised regulations from the original irregularities of the ten variable into six cate

12、gories. Regulations of violation of the party constitution, to the detriment of the constitution authority and discipline behavior lacks necessary and serious responsibility accountability, and there is a discipline method. Now we adapt fully in accordance with the law of governing the country by la

13、w and in accordance with the regulations governing the party to take them apart, the legal attribution of law and discipline discipline. So the prominent characteristic is the discipline method separately, Ji The provisions of the Ordinance to discipline the table, make the law do not put inside the

14、 tube, to avoid our discipline or into party public security. Dont relate to the field, thus avoiding the repeated cross. Three is a reflection of strengthening the partys discipline construction of the latest achievements. New mainly reflect the partys eighteen years central resolutely implement th

15、e eight provisions, and resolutely against the four winds and so on, these new wrote the. For example, said the new in the implementation of the central eight of the spirit, a lot of opposition to the four winds wrote a clean Ji Law chapter, it represents the comprehensive strictly Party A the lates

16、t achievements. Party members if there is illegal and even criminal behavior, how to pursue disciplinary responsibility? According to Ji from the revision principle, where the state laws and regulations have stipulated content, will not re complex provisions. Revision of the Communist Party of China

17、 deleted 79 and criminal law, repeated terms of Public Security Management Punishment Law, and other laws and regulations. However, deletion law has provisions and not that the act is no longer the discipline, no longer be given disciplinary punishment. According to the party constitution, Party mem

18、bers have exemplary compliance with the obligations of the state laws and regulations, violations of the laws of the country are discipline Behavior. Remove the overlap with the discipline of the content and how to pursue party illegal and even criminal behavior of Party discipline and responsibilit

19、y. difference between five different conditions, with special provisions to stipulate, to achieve effective convergence of laws and discipline. It should be said, the revised in the Ji method to separate the stickRefers to the provisions of regulations set at the same time, through the special provi

Industrial automation technology has gradually matured, as mature a technology line has been rapid developmen

21、t in industrial automation as a separate subject. Manipulator application began to filter into welding, logistics, mechanical processing, and other industries. Especially at high or very low temperatures, full of poisonous gases, high radiation case, robot in similar circumstances showed great use a

22、lso brings great convenience to the staff. Precisely because of this robot to get peoples attention began to be a high degree of development. Labor rates, working conditions, labor intensive aspects of promoting development. Both at home and abroad to develop the PLC (programmable logic controller)

23、is in various special circumstances and under special conditions set for mechanical devices. Now turned on the development of the microelectronics automatic control technology and the rapid development of the trains, the success of PLC hardware software and simulation control win big and successful

24、development, now continues to develop as a factory automation standards. Because robots are good development of the technology makes a good optimization of productive capital, and robot shows this unique advantages, such as: has good compatibility, wide availability, hardware is complete, and progra

25、mming that can be mastered in a short time, so in the context of industrial PLC applications became ubiquitous. Manipulator in many developed country agriculture and industry has been applied, such as the use of mechanical harvesting large areas of farmland, repeated operations on the high-speed lin

26、e that uses a robotic arm, and so on. Today, the high level of automation combined with restrictions on the manipulator development level is slightly lower than the international. The design is mainly arm welding machine by PLC Automation control. This of design let designers on in school by learn o

27、f has a must of consolidation, understand has some usually didnt opportunities awareness in world range within some leading level of knowledge has has must awareness, hope designers can in yihou of design in the can success of using in this design in the proceeds of experience 1.2 manipulator in bot

29、n standards, and its importance can be seen. Now original robotic arm spent most of mass production and use on the production line, which is programmed robotic arm. As the first generation of manipulator position control systems main features, although not back several generations that can detect th

30、e external environment, but can still successfully complete like welding, painting, delivery as well as for materials simple movements. Second generation mechanical arms are equipped with sensors and manipulators have the environment there is a certain amount of sense, when the mechanical arm is to

32、工程提供了可借鉴之处。Abstract：The main bridge of the sixthhanjiang bridge in Wuhan is a self-anchored suspension bridge with double pylons and double cable planes. The main pylon pile foundation with large diameters is extremely long.The maximum drilling depth is 120 m. The crossing formation is complex and t

33、he construction is very difficult and the construction periodis very short. The construction quality and time planning cannot be guaranteed if the single drilling technology was used in this project. So, based on the engineering characteristics of this project, we use the muti-machine drilling techn

34、ology. That is the auger drilling overburden and airlifting reverse circulation rotary drilling strata. The muti-machine drilling technology not only can increase construction efficiency, but also can guanatee quality.It offers reference for dealing with similar problems in future.关键词：多机成孔工艺；大直径超长桩；

Then, relevant provisions refers to what? The understanding, which is mainly in 2001

47、 the central Issued on party and government organs of the staffs personal investment in securities provisions. In accordance with the provisions of this, in party and government organs workers can be buying and selling stocks and securities investment funds, but in buying and selling stocks and secu

52、 the central Organization Department and the General Political Department jointly issued , which clearly stipulates that leading cadres are not allowed to participate in the initiative to set up (not by the Civil Affairs Department) fellow alumni, between comrades association or organization shall n

Therefore, Party member

56、an see them now, however these two control modes (relay and discrete electronic circuits) are these fatal flaws: (1) cannot adapt to the complex logic control, (2) only for the current project, the lack of compatibility and (3) not reforming the system with equipment improvements. Spring for the dev

In terms of controlling the computer showed his two great advantages: (1) each of the hardware can be installed on one or m

58、ore microprocessors; (2) the official designer of the software writing content control is all about. Now in several ways in the context of industrial automation can often be seen in three ways: (1) Programmable Logical Controller (referred to as IPC); (2) Distributed Control System (DCS for short),

59、and (3) the Programmable Logical Controller (PLC for short). 2.1.2 PLC and the IPC and DCS contrast contrast 1, each of the three technologies of origins and development requirements for fast data processing makes it invented the computer. The men brought in terms of hardware there, using a high lev

So the computer can effectively control is used to control and meet its speed, on the virtual model, real-time and in computational requirements. Distribut
